Natural Antibiotic for a Goat Kid?

Hi...we have Nubian cross goats.  One of our kids was banded.  He is 6 1/2 weeks old.  His 'jewels' fell off yesterday, and the site looks good, not red or inflamed.  A couple of days ago he started to act funny - not really eating,  and he keeps lifting his hind legs and putting his snout between his hind legs.  Could he have developed some sort of infection?  We have checked his eyes, checked his temp - (104, so maybe one degree over normal), checked for worms.  He seems to be urinating and pooping normally, although his mom is not letting him nurse as much.  He hasn't been eating much that we can see.  Is there something natural we can give him, in case he has developed an infection?

Both garlic and oregano are natural antibiotics and can be given to goats.

Maybe the site is itching as part of the healing process?  Does the site look red and inflamed or maybe just red from healing? What do you usually use for cuts and scrapes for your goats?  

Maybe the mother is trying to wean him. Since it has been several days since you posted, how is he doing?

Thank you for your response, Anne.

There does seem to be a large scab where his 'jewels' fell off.  I am wondering if the band caught a little too much skin, and it is uncomfortable now that they have come off.  Hopefully that is all that it is, and once the scab comes off the skin will stretch a little more.  He doesn't have a temperature, so we don't think it is an infection.  He is just not acting totally normal and seems to keep lifting his back legs and nudges that spot with his nose, so maybe it is itchy.  He is pooping and peeing normally.
